According to The Mirror, Horan and The X Factor USA judge are reportedly keeping their romance "casual" due to their hectic work schedules.
A insider told the newspaper that Demi has since admitted that she is seeing the Irish hunk, adding: "Demi's told the guys backstage she and Niall are loosely dating - it's casual but they are definitely dating, albeit long-distance."
Lovato has also apparently addressed her feelings for Niall, with the tabloid quoting the 20-year old beauty as saying: "He has a lot of great qualities. He is an amazing listener and makes me laugh a lot, two of the main qualities I look for.
"He knows I have a little crush on him, and we enjoy having dinner when we get the chance. We speak and message all the time."
She continued: "I don’t want a relationship over Skype; we are both in a place where we feel zero pressure to rush.
"We share the philosophy that the right one is worth waiting for.”
